WARNING - ELECTRICAL PRECAUTIONS
All wiring, electrical connections, and system grounding must
comply with the National Electrical Code (NEC) and with any local
codes and ordinances. Employ a licensed electrician.
FOR DUAL VOLTAGE MOTORS:
Voltage change instructions are located on motor label or on
wiring access cover.
This pump is suitable for installations where the vertical distance
from the pump to the water level does not exceed *25 ft.(7.6m),
including friction loss. In off-set installations, friction losses in the
suction pipe must be taken into consideration.
*Varies with elevation above sea level.
a) PUMP LOCATION: The pump should be installed in a clean,
dry and ventilated location which provides adequate drain-
age and room for servicing and protection from freezing
temperatures. It should be bolted down evenly on a good
foundation, preferably concrete, to prevent the development of
unnecessary stress. Locating the pump as close as possible
to the source of water supply reduces the friction losses in
the suction pipe and provides for maximum capacities.
b) SUCTION PIPE: It is recommended that only new clean
pipe or hose be used and the size be the same as that of
the pump suction tapping. If the pump is installed any ap-
preciable distance away from the source of water supply,
the suction pipe should be increased by one size (this would
increase the priming time). The suction pipe must always
slope upwards from the water source to the pump to avoid
air pockets in the line. In cases where the pump has to be

WARNING - RISK OF ELECTRICAL SHOCK
• Have an electrician provide electrical power to the motor.
• Motor must be grounded and terminal cover in place to
reduce electrical shock hazard.
• Keep motor operating area as dry as possible.
• Always disconnect power before servicing.
• Not investigated for use in swimming pool areas.

reprimed often and it is not necessary that a lot of water be
delivered, it is advisable to use a 90° or 45° elbow on the
suction line. This enables the pump to prime sooner and also
prevents kinking of the hose. In cases where a maximum
volume of water is required over a prolonged period of time,
the suction line should be led almost horizontally to the
pump. Thread compound should be used on all pipe joints
and connections should be thoroughly tightened. A strainer
should be connected to the bottom end of the suction pipe
and it should be well submerged at all times.
c) WIRING: It is recommended that a separate circuit be used
from the distribution panel to the pump unit. A properly fused
disconnect switch is to be installed in the line, making sure
that the correct gauge of cable is used to carry the load. Very
long leads will require a larger cable. An electrician should
be employed to do the wiring.
